My only real issue with soccer is extra time. From my limited understanding of it, it seems pretty arbitrary, no? And are both teams notified in advance as to if there is going to be extra time? Because i can see a team being frustrated with it if they have a lead or something.
Are you people honestly unaware of how extra time works in Soccer/Football?
Time is added on when teams waste time, have injuries, score a goal or make substitutions.
This time is then presented for all to see via a giant marker on the halfway line at around the 89th minute. The referee then uses this number as the minimum amount of time allowed for extra/injury time.
